CARRIAGE-CURTAIN BUTTON.

SPECIFICATION forming part of Letters Patent No. 323,131, dated July 28, 1885.

Application filed May 11, 1885.

To all whom it may concern,-

Be it known that 1, JAMES G. ENGLISH, of New Haven, in the county of New Haven and State of Connecticut, have invented new Improvements in Carriage Curtain-Buttons, and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a perspective'view of the button; Fig. 2, an under side view; Fig. 3, a longitudinal central section; Fig. 4, the plate, the spring, and the collar detached, showing the under side of the plate; Fig. 5, a transverse section at right angles to the section Fig. 3, Fig. 6, a face view of the fastener.

This invention relates to an improvement in that class of fastenings for carriage-curtains such as are in the form of a turn-buttonthat is to say, a plate fitted for attachment to the point where the curtain is to be secured, with a thin turn-button attached thereto adapted to receive a slit of a button-hole-like character in the curtain, and so that after the slit in the curtain has been passed over the button portion the button may be turned to a transverse position across the button-hole, and there by prevent the accidental disengagement of the curtain. These buttons are usually provided with some device to engage the button when it stands in a position to receive the curtain, and also to engage it when it stands in the fastening position. It is to this class of fastenings that my invention particularly relates; and it consists in the construction as hereinafter described, and more particularly recited in the claim.

A represents the plate or base by which the fastening is to be secured. It is constructed in some cases with rivets a upon the under side, by which to attach it, or may be constructed with holes, through which rivets or screws may be introduced.

Upon the outer face of the plate is a b'oss,B, which in thickness is equal to the thickness of the curtain to be secured. It is of elliptical shape, as seen in Fig. 6, so as to be adapted to pass through an elongated opening in the curtain.

(No model.)

C is the turn-button, which is arranged upon the boss B, and is constructed with a pivot, b, from its under side, extending through a central hole in the boss, and so that the turn-button may be rotated on the boss in a plane parallel therewith, and as indicated in Fig. 6.

Upon the under side of the plate A is a recess, d, here represented as circular in form and concentric with the pivot. In the side of this recess are one or more notches, e.

D is the spring, which is cut from sheet metal of any suitable shape, (see Fig. 4,) and with a projection, f, corresponding to the notch or notches e in the recess in the plate A, and so that when set into the recess the projections f will enter the corresponding notches in the plate, and thereby prevent the spring from rotating in the recess. Through the spring D is a central opening, h, through which the pivot b passes.

E is a collar set onto the pivot b outside the spring, and so as to bear thereon. The pivot 11 extends through the collar E, and is riveted thereto, so as to make such engagement with the collar that the collar willturn with the button in its rotation. The collar E at certain points is constructed with recesses t Z, the recessl being at right angles to the recess The spring D is constructed with downward projections an, adapted to enter the recesses in the collar E, as seen in Fig. 5. The recesses are of concave shape, and the projections m on the spring of corresponding shape. The position of the recess i l in the collar with relation to the button and to' the projection m on the spring is such that when the button stands in the plane of the boss the recessest' will come into line with the projections m of the spring, and so that the said projections will enter therein, as seen in Fig. 5, thus holding the button in the proper position to receive the slit in the curtain; or when turned at right angles thereto the projections at will fall into the recesses Z in the collar, and thereby hold the button in the transverse or locked position; but while the turn-button will thus be held in either position'the shape of the recesses in the collar and theprojections on the spring are such that a little force applied to the button will overcome the engagement be tween the spring and collar, so that the collar may be turned and compress the spring until the button arrives at another position where the collar and spring will re-engage.

The fastening in many cases is attached to the leather forming the top of the carriage; but, because the spring is covered by the collar E, there is no liability of the flexible leather interfering with the free action of the spring. The outer surface of the collar being smooth and plain, cannot engage the material to which the fastener is applied, to interfere with the proper working of the button, a difficulty experienced in the use of this class of fastenings, and which my invention is particularly designed to overcome.

Instead of making the recess in the collar and the projections in the spring, this order may be reversed, it only being essential that there shall be a projection on the one and recess on the other, so that in the rotation of the turn-button the collar and spring will make engagement at predetermined points, and so as to lock the said button at such predetermined points.

From the foregoing it will be understood that I do not claim, broadly, a carriage-curtain button, arranged to turn upon a base-plate, and so that after the hole in the curtain has been set over the button the button may be turned transversely across the hole, and there locked by a spring arranged in a recess on the reverse side of the button, as such, I am aware, is not new; but in such construction the spring has been exposed to contact with the flexible surface to which the fastener is necessarily attached. Again, in previous constructions the spring has been attached to the button and so as to rotate with it, which construction does not allow the same freedom of the spring as when it is arranged stationary in the base and independent of the button, as in this application. By this improvement difficulties hereinbefore pointed out are avoided.

I claim The herein-described fastener for carriagecurtains, consisting of the plate A, adapted for attachment to the point where the curtain is to be secured, said plate constructed with the boss B upon its face and with a recess, d, upon the reverse side, the recess having one or more notches, c, in its side, combined with the turn-button O, constructed with a pintle, 1), extending through a central opening in said boss, a spring, D, arranged in said recess and adapted to engage the side of the recess to prevent its rotation, and the collar E upon said spring, and secured to the pivot so as to rotate with the turn-button,the said collar and spring, the one constructed with notches and the other with corresponding projections, whereby said spring will engage said collar at certain predetermined points, substantially as described.
